This says the Knieper car was a RamAir1

To stay over W/P=9.50 it has to be either an unfactored RA1 at 325hp (LOL) or factored to maybe 340hp but no higher, even adding weight for the T400 trans which is not in today's class guide.

Per what Dwight Southerland said, at least by late 1968 the RA1 Firebird was factored to the GTO's 360hp so maybe this was before that time.

I guess there's no way to externally tell a 67 RA Firebird from a non-RA?
So Heath is still a question.
